Point clouds
Data has been treated through the following steps:
- Split between sea bottom and vegetation using intensity
- Split between water column noise and vegetation using intensity
- Statistical outlier removal
- Final ‘cleaning’
Ølberg South sea bottom points
Ølberg South vegetation points
Ølberg North sea bottom points
Ølberg North vegetation points
Rasters
From our point clouds, we create Digital Terrain Models (DTM) and
Digital Surface Models (DSM) of our sea bottom and vegetation canopy,
respectively
- Using interpolation methods from ARC GIS Pro
Vegetation canopy depth (DSM)
Canopy height (DSM - DTM)
Ground truth v. LiDAR canopy height

Bathymetry (DTM) from Otter
LiDAR v. Otter bathymetry
